Good Evening FORKERS

Posted: 28/04/2013 at 18:37

Got two rows of spuds planted (at long last!) and lots more potting-on done.  Also found spaces for another Ribes odoratum and a Viburnum x bodnantense ‘Dawn’ in a long border.  No idea where I'm going to put all of the stuff still in the GH - looks like I'll be giving lots of plants away again (which is obviously why I need to keep buying pack after pack of small pots every year, now I come to think of it!)  

Dahlia - white substance on shoots?

Difficult to say what will work as we can't identify exactly what it is, but assuming a fungus, I'd try a copper-based one first with Bordeaux mixture probably being the easiest to get.  If it doesn't work, it will still be useful for other things - see the RHS advice on fungicides for garden use:

I'd go with an obelisk then you can grow climbers through it.  If the plants your try don't suit, easy enough to whip them out and plant different ones.  The cypress idea would look impressive, too.

Hi Tootles, At the moment I'm putting the pots in the GH during the day, but bringing back indoors at night.  Last night my max-min thermometer in the GH said it went down to 2.3C, which would have done them no good at all.  I agree with Italophile about the temperature range.  If you can afford a max-min thermometer (under £10), they are well worth having in a greenhouse.

Invasive roots in veg patch

Are you sure they are roots and not fungal mycorrhiza?  Those are usually very weak though, except for honey fungus.

Hi blackest, I think that's all we can do for now.  I do hope this isn't an intentional change because I have seen some sites do this because they run out of server space.  Unfortunately, relying on external photo-hosting sites does mean that, over time, photos inevitably disappear from the forum threads as folk often unsubscribe from the photo-host sites or delete those pictures when they leave the forums they posted the links to.  There's nothing worse than finding a thread of interest then discovering the photos being talked about are missing!

Black spot on roses

Posted: 27/04/2013 at 12:49

Pentillie, Black spot is a fungus which affects the leaves and is transmitted by spores, so watering anything on the roots won't help.  All you can really do in addition to the things you have already mentioned is to more regularly spray the leaves and keep them really well fed.  On my clay soil, it doesn't matter what I do so just have to put up with it.  One rose "Peace" is about 40 years old and gets it really bad, but is still growing as strongly as ever.  If you see signs of black spot on the actual stems, cut them back really hard early next spring and it will lessen the effect for a couple of years.  Try and keep the roses as open in structure as possible - wine goblet shaped is recommended, as the more light and air that can get to the middle of the bushes, the better.

The JF might work if watered on roots of plants affected with vine weevils though.

Your top performing BLUE clematis

Posted: 27/04/2013 at 11:40

What shade of blue do you prefer, and what type (ie group1, 2 or 3?)  Many of the most reliable large flowered (gp2) types are on the purple side.

Same here - seems they are well behind this year.
